(crise-ss) This inventionrelates to hair wavingimachines, and particularly the clamp and ovenassembly which is used to directly apply heat to strands of hairwhichare wound upon the well known 3,5 hair-receiving spools, and theprimary object of this invention is to provide a unique and novelkhairtreating oven wherein the hood thereof is `positively ailxed to thevise in such manner that :the jaws of the .viseare maintained againstaccidental` displacement during the application of .heat and the sealbetweenvise and hood is unbreakably established. -v .1 o

Another object of the present invention is to `provide a hair treatingovenfor permanent wave 13715 machines using steam as a heating elementhaving aimoisture-absorbing gasket `that is formed in a particularmanner so as to present a condensate absorbing element within the oventhat `precludes the` collection of moisture at any time.

Further specific aims of, this invention will appear during the` courseof the following specification,referring `to the accompanying drawing,

wherein: i l

'y

Figs. 1 to 5 inclusive illustrate `the hair "treating oven `without thenovelgasket associated therewith, it must be understood that the gasketmay be applied without altering" the `structure of the oven in lanyfmanner whatsoever and this 5,0`gasket might be used or" not, as`the-operator ideems advisable.` i i Inpreparing the hair for apermanent wave, same is blockedoi `and the vise shown in Fig. 6appliednear the scalp so that the free ends o the ...5.5 hairg might `bewound around spool 10 whichl-is To'preolude this condensate Vthe scalp,a moisture-absorbing `gasket 48 is con- 1 00 rotatably supported by thisvise, thatcomprises a pairof strips 12, each covered by a jacket ofresilient material 14 which, when the strips 12 are drawntogetheras'shown in Fig. 4, will grip the strandswof hair therebetweento positively preclude slipping. Strips 12 are hingedly secured togetherat one end by a link 16 and asimilar link 18 at the other end of strips12 supports a manually operable latch member 20 that co-oper- `ates witha notch 22 formed in one strip 12 for 65 the purpose of securingtogetherboth strips 12 after the hair has been passed therebetween.

In the instance shown, each link 16 and 18 respectively is i U-shaped intransverse cross section and at least one wall thereof is provided witha tapped opening 24 for the reception of a hereinafter describedscrew-threaded clamping element. f Y i Link 16 is likewise provided witha tapped opening 26 for ra similar purposeand strips 28 .'16

and `30 rigidly secured to the jaws of the vise present1 tongues 32vand34 respectively which combine with rims 36and 38 of spool 10 torotatably secure said spool in place. Tongue 34 progressively engagesdetents 39 as spool 10 is 80 rotated and precludes unwinding of thespool after the strand of hair has been tightened thereon. As iscustomary, aclamping finger .40 is .providedron spool `10 so that theends of .the

strand :ofhair beingwound might be secured es in place before the spoolis rotated.'

A sheet metal hoodV 42 is carried by strips 12 i and joins with thelatter in completely housing 'spooll and its associated parts. This hood42 must be secured `in place with sufcient force to prevent escape ofair therefrom because steam is applied to the hair wound upon spool 10by passingthe steam intointake port 44 that `is :formed `throughthe bossand side wall of hood 42. An-

other similar boss 46 provides an exit :for the A95 "steam inorder toset upV complete circulation and `obviously a certain amount of.condensation will take `place duri-ng the operation. Y

from contacting templated. This gasket 48 may `loe made of ordilnaryblotting paper or similar substance and.

should be formed'a's distinctly illustrated in Fig.

A`8; `gasket is applied before hood 42 is moved to position andunderlies the edgel thereof. In

' other words, it is-interposed between hood 42 and f the .resilientmaterial which circumscribes strips -1`2i Walls`150 are set off on thenormally planar gasket 48 between openings 52, one of which is formedthrough the gasket adjacent each -end. 110

which effects connection between vise and hoods.

The unique manner of interconnectingvhood 42 with strips 12 is embodiedin the clamping ele,

ment 60 that has a knurled head 62 preferably formed of iibrous materialthat ductor of heat. A screw-threaded shank 64 exe tends through bearing66 that is rigid with hood 42 and this bearing permits' free -rotationof the entire clamping element 60. Shank 64 extends into tapped opening24 of link 18 and a collar 68 secured intermediate the ends of shank64-limits longitudinal movement of element 60 in bearing 66.

Openings 70, formed through the walls of bearing 66, are not tapped andthe end of shank 64 is tapered as at '72 so that the clamping element60, one of which is located on each end of hood 42, may be quickly movedto the operative position so that it will draw hood 42 down againstgasket 48 or resilient covering 14, as the case may be. Tightening theseclamping elements will set up a positive seal between parts of the hairtreating oven and when steam is passed through the oven no leakage will,occur and a quick disassembling may take place merely by unscrewingclamping elements 60. Insulating strips 74 are provided to insure thatno objectionable heat will be conducted from the oven to the scalp,

An oven for treating hair that is made in accordance with the foregoingwill be found to be positively assembled when the hood is in place. Noaccidentalopening of the vise can occur because the hood vand itsassociated clamping ele- Yments will preclude moving apart of links 16and 18. Any suitable materialsv might be used in constructing the partsof thevoven, but it has been found that rust-resisting metal is best informing the metallic parts of the oven.
